||The rigorous thesis provides with an insight into the issue of regional problematic in the European Union. Theoretical background illustrating basic facts about institutional structure, historical development and justification for the existence of common structural policy, and further about possible welfare influence of this redistribution instrument, is followed by analysis of income disparities across the EU, both at the national and regional level, and their development during recent two decades. Redistributive effects of the EU regional expenditures are evaluated, in terms of the extent to which they have been aimed at weaker rather than more prosperous parts of the Community. In consequence, effectiveness of RP is examined; regression models for regional disparities try to show whether there has been a positive relationship between the EU structural resources and narrowing of averaged income gaps across the Union. My practise is slightly different from most of the empirical work on this issue as I try to explore RP effects both for particular EU countries and for the EU as a whole.
